Product Description
The Allen-Bradley 140G-M5H4-D63 is a robust, 800-Amp, four-pole molded case circuit breaker designed for demanding, high-voltage (1000V) industrial applications, offering reliable protection with a 50kA interrupting rating, advanced electronic LSI protection, and the ability to withstand 8kV impulse voltages, while also being manageable for installation at 33.29 pounds and providing a long operational life.
Is Your Device Showing These Signs?
The Allen Bradley 140G-M5H4-D63 molded case circuit breaker commonly exhibits issues such as nuisance tripping due to incorrect overload settings or thermal magnetic trip unit malfunction. Field failures include contact erosion from repetitive high fault current interruptions, leading to reduced interrupting capacity. Diagnose communication faults stemming from corrupted Modbus RTU parameters or a faulty communication module. Inspect the breaker for mechanical damage affecting the operating mechanism and ensure proper torque on all terminal connections to prevent overheating and potential electrical fires. Verify proper coordination with upstream and downstream protective devices to avoid cascading failures during short circuit events.
